Technical Field
[0001] The utility model relates to the technical field of electric blankets, in particular to an automatic temperature-control electric blanket. Background Art
[0002] Electric blanket, also known as electric mattress, is a contact electric heating device. It weaves or sews special soft-cable electric heating elements with standard insulation performance into the blanket in a snake-like shape, and emits heat when powered on. Other products with similar working principles and structures to electric blankets include warm compress blankets, electric mattresses and electric heating pads. Nowadays, electric blankets can achieve the effect of automatic temperature control, which can keep the electric blanket within the heating temperature range set by itself, making it more convenient to use.
[0003] As we all know, electric blankets need to be folded and placed when not in use. When they are taken out for use after being folded for a long time, the internal heating wire may break. Electric blankets are usually made of two layers sewn together, and the breakage of the heating wire is not easy to detect and cannot be replaced quickly. Moreover, the replacement requires the entire blanket to be replaced, which has a high maintenance cost. Utility Model Content

Specifically, the purpose of the utility model is to provide an automatic temperature-controlled electric blanket to solve the problem that the breakage of the heating wire is difficult to detect and cannot be quickly replaced as mentioned in the above background technology.
[0005] To achieve the above objectives, the utility model provides the following technical solutions: an automatic temperature-controlled electric blanket, comprising a first blanket body and a second blanket body, a connecting component is provided between the first blanket body and the second blanket body, and a heating component is provided on the upper surface of the first blanket body.
[0006] Preferably, the connection assembly includes a Velcro hook surface sewn to the upper surface of the first blanket body, and a Velcro fleece surface is sewn to the lower surface of the second blanket body, and both the Velcro hook surface and the Velcro fleece surface are rectangular frame structures.
[0007] Preferably, the heating assembly includes a plurality of heating wires arranged on the upper surface of the first blanket body, the plurality of heating wires are distributed in a serpentine shape, a conductive silicone tube is connected in series between the plurality of heating wires, and the plurality of heating wires are electrically connected to a temperature controller through electric wires, and a plurality of temperature sensors are fixedly arranged on the upper surface of the first blanket body.
[0008] Preferably, the bottom surface of the conductive silicone tube is fixed to the upper surface of the first blanket body, both ends of the conductive silicone tube are respectively provided with sockets that fit with the ends of the heating wire, and the upper part of the conductive silicone tube is electrically connected to a light emitting diode.
[0009] Preferably, several of the temperature sensors are electrically connected to the temperature controller.
[0010] Compared with the prior art, the beneficial effects of the utility model are:

If the heating wire is broken at a certain place, the light-emitting diode on the conductive silicone tube connected to the end of the heating wire at that place is in an extinguished state, and the broken position of the heating wire can be found. At the same time, after the electric blanket is powered off, the two ends of the damaged heating wire can be pulled out of the slots at the end of the conductive silicone tube for replacement or repair.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-5The utility model provides a technical solution: an automatic temperature-controlled electric blanket, comprising a first blanket body 1 and a second blanket body 2, a connecting component is provided between the first blanket body 1 and the second blanket body 2, and a heating component is provided on the upper surface of the first blanket body 1.
[0020] The connecting component includes a Velcro hook surface 3 sewn to the upper surface of the first blanket body 1, and a Velcro fleece surface 4 is sewn to the lower surface of the second blanket body 2, and both the Velcro hook surface 3 and the Velcro fleece surface 4 are rectangular frame structures, which facilitates the disassembly or separation of the first blanket body 1 and the second blanket body 2 and the maintenance of the interior.
[0021] The heating assembly includes a plurality of heating wires 5 arranged on the upper surface of the first blanket body 1, the plurality of heating wires 5 are distributed in a serpentine shape, and a conductive silicone tube 51 is connected in series between the plurality of heating wires 5, and the plurality of heating wires 5 are electrically connected to a temperature controller 6 through wires, and a plurality of temperature sensors 7 are fixedly arranged on the upper surface of the first blanket body 1, so as to facilitate automatic temperature control according to the set temperature.
[0022] The bottom surface of the conductive silicone tube 51 is fixed to the upper surface of the first blanket body 1, and both ends of the conductive silicone tube 51 are respectively provided with plug holes 52 that fit with the ends of the heating wire 5, and the upper part of the conductive silicone tube 51 is electrically connected to a light-emitting diode 53, so that the heating wire 5 can be plugged in and out through the plug hole 52, and the light-emitting diode 53 can be used to observe whether the heating wire 5 is damaged.
[0023] A plurality of temperature sensors 7 are electrically connected to the temperature controller 6 , so that the temperature sensors 7 can sense the temperature and transmit signals to the temperature controller 6 .
[0024] Working principle: When using the automatic temperature-controlled electric blanket, firstly, the electric blanket is powered on, and the required temperature of the electric blanket is set through the temperature controller 6, and the temperature controller 6 controls several electric heating wires 5 to be electrically connected to increase or decrease the temperature. When the electric blanket is heated to the set temperature, the temperature sensor 7 senses the temperature and sends a signal to the temperature controller 6, and the temperature controller 6 controls the electric heating wires 5 to stop generating heat. Since the conductive silicone tube 51 has good conductivity and heat resistance, it has a bendable effect while connecting several electric heating wires 5, and after the conductive silicone tube 51 is powered on, the light-emitting diode 53 inside it lights up;
[0025] When the electric blanket is folded and stored and the internal heating wire 5 is broken, by tearing off the Velcro hook surface 3 on the upper surface of the first blanket body 1 and the Velcro fur surface 4 on the lower surface of the second blanket body 2, it can be observed that the light-emitting diodes 53 along the power-on direction of the heating wire 5 are all lit. If the heating wire 5 is broken at a certain place, the light-emitting diode 53 on the conductive silicone tube 51 connected to the end of the heating wire 5 at that place is in an extinguished state, and the broken position of the heating wire 5 can be found. At the same time, after the electric blanket is powered off, the two ends of the damaged heating wire 5 can be pulled out of the slots 52 at the end of the conductive silicone tube 51 for replacement or repair;
[0026] In summary, when the electric blanket is used, not only can the temperature be automatically controlled, but also the damaged heating wire 5 can be easily checked and disassembled and replaced, so it is convenient to use.
